Enrichment

Found in PeakGroups

GitHub Link

A weighted average of the fraction of labeled atoms for this PeakGroup (e.g. the fraction of carbons that are labeled in this PeakGroup compound). Calculated on a per-element basis (e.g. "C" enrichment and "N" enrichment are independent of each other).

For each element: Sum of all (PeakData.fraction * PeakData.labeled_count) / PeakGroup.Compound.num_atoms(PeakData.labeled_element)

See this Example of Enrichment Fraction and Abundance Calculation.
